Answer :
Answer:
No. of complete revolutions = 20
Step-by-step explanation:
Given:
Distance covered by the bicycle = 40 m
Radius of the bicycle wheel = 32.5 cm = 0.325 m
Conversion:
⇒ [tex]1\ cm=\frac{1}{100}\ m[/tex]
We have to find the number of revolution the front wheel make.
Let the no. of revolution be "N" .
As we know that:
Circumference times no. of revolution = Distance covered by circular objects.
Circumference = 2πr
So,
⇒ [tex]Distance\ covered=N\times 2\pi (r)[/tex]
⇒ [tex]\frac{Distance\ covered}{2\pi(r) } =N[/tex]
⇒ Plugging the values.
⇒ [tex]\frac{40}{2\pi(0.325) } =N[/tex]
⇒ [tex]\frac{40}{2.04} =N[/tex]
⇒ [tex]19.6=N[/tex]
Approximated to 20.
Number of complete revolutions,the front wheel make = 20
